Overview

VR-Training: Adapting Virtual Reality Training Applications by Dynamically Adjusting Visual Aspects

  • Survey: Cross-sectional Study with Longitudinal Elements

  • 2 Cohorts (Linne and Dame)

    – 21 Participants in Linne, 81 in Dame (with overlaps)

    – 9 Rounds of Training for Dame and 11 for Linne

    – Grouped into Adative and Non-Adaptive Training versions

    – 2 Rounds of Test per Cohort (Linne: VR, Dame: Real-world)

  • Timeframe:

Terminology

Stress indicators:

  • Answer Q1: Perceived cognitive load ({1,2,3,4,5,6} with 1 very low and 6 very high)
  • Answer Q2: Perceived physical load ({1,2,3,4,5,6} with 1 very low and 6 very high)

Terminology

Physiological Measurement Data (PMD)

  • Heart rate (HR): Heart rate beats per minute (bpm)
  • IBI: Interbeat interval (ms)
  • SDNN: Standard deviation of the NN intervals
  • RMSSD: Root mean square of successive differences
  • SCL: Skin conductance level (µS (micro Siemens))
  • SCR frequency: Frequency of the skin conductance response
  • SCR amplitude: Amplitude/strength of the skin conductance response (µS/µmho (micro Siemens/micro Ohm))
  • SCR_rising_time: Rising time of the skin conductance response
  • Blink rate last minute: Blink frequency per time unit
  • Saccade amplitude: Degree of eye movement
  • Saccade velocity: Speed of sudden eye movements
